E22: Hyperfunction of pituitary gland

The hyperfunction of the pituitary gland refers to a group of conditions characterized by an overactive pituitary gland, which is a small bean-shaped gland located at the base of your brain. This gland is responsible for producing various essential hormones that control functions from growth and metabolism to blood pressure and body temperature. When the pituitary gland is overactive, it produces an excessive amount of these hormones, which can lead to various health problems depending on which hormones are overproduced. Common symptoms that might suggest an overactive pituitary gland include unexplained weight loss or gain, fatigue, mood changes, and changes in body hair or skin. In some cases, issues with vision and headaches might also occur. The primary causes normally link to tumors or growths on the pituitary gland itself, however, certain genetic conditions, infections, or injuries can also contribute to pituitary hyperfunction. The progression of these conditions highly depends on the underlying cause and the hormones affected.
